OILING-BOX FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 499,431, dated June 13, 1893.

Application filed March 10, 1893. Serial No. 4651 N m l To all whom it may concern.-

Be it known that I, JOSEPH J UDD, a citizen of the United States, residing at Ansonia, in the county of NewHaven-and State of Connecticut, have invented certain new and useful Improvements in Oiling-B'oxes for Rolling- Mills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to produce an oiling box for use in rolling mills, my novel oiling box being especially adapted for use in cold rolling sheet-metal, the special object in view being to provide a box which'will render waste of oil practically impossible, the surplus oil taken up by the strip of metal being returned to the box immediately, the operation in use being such that all the oil in the box may be used up before renewal, and furthermore should a dry box be required the water may be drawn ofi at any time, leaving the oil in the box but below the coil of metal so that the metal will pass to the rolls perfectly dry.

In the accompanying drawings forming part of this specification Figure 1 is a transverse section on the line ac min Fig. 2, and Fig. 2 is a longitudinal section on the line y y in Fig. 1.

1 denotes the rolls which may be of any ordinary construction, 2 denotes the box which is made highest on the side toward the rolls and lowest on the opposite side. The box is provided on three sides with an inwardly inclined flange or trough 3 which is provided at its lowest point, see Fig. 2, with an opening 4 leading into the box. The object of this flange or trough is to insure that any oil that may spatter outside of the box in use will be caught by the flange or trough and conducted back into the box again. Under the rolls is a drip trough 5 the lower end of which rests upon the edge of the box and which is supported by a cross piece 6 or in any suitable manner. All the oil that is pressed from the metal by the rolls in the act of rolling will drop down upon this trough and pass back into the box.

7 denotes a coil of metal that is being rolled and which is coiled as usual upon a drum or block 8. The coil of metal rests upon a holder 9 within the box said holder consisting of a strip of metal the center of which curves downward to receive the coil and the ends of which curve over cross pieces 10 by which the holder and coil are supported.

11 denotes a pipe which extends downward within the box nearly to the bottom thereof, the upper end of said pipe extend-ing upward some distance above the bottom of the holder and then outward through the side of the box as clearly shown in Fig. 1.

In use water is poured into the box and oil is poured on top of that. The oil will of course lie upon the surface of the' water. So far as the operation of the box is concerned it makes no difference how thick the layer of oil is upon the top of the water. It is obvious that the liquid within the box can only rise to the top of pipe 11, the liquid line being indicated by 12 in both figures. Water may or may not be kept continually flowing into the box. It is obvious that if enough water passes into the box to raise the liquid within it above line 12, water will immediately pass out through pipe 11 until the liquid line is normal again. It will be obvious moreover that all the liquid that can pass out through pipe 11 must enter said pipe below the line indicated by 13. As already stated the depth of the layer of oil is immaterial, it being contemplated of course that the water line shall be anywhere between thelines 13 and 12 indicated in the drawings, and that there shall be oil enough upon the surface of the water to make the liquid line approximately at 12. Of course in use if water is not kept flowing into the box, or is admitted occasionally only, the liquid line will in time drop down below the arbitrary line 12 indicated in the drawings, some of the oil being of course consumed in use and the water being taken up more or less by evaporation.

In use both oil and water are taken up by the strip of metal and pass to the rolls, the drip from the rolls however dropping upon trough 5 and being conducted back into the box. This device does its Work perfectly without attendance and entirely does away with the necessity of mopping the strip of metal as it is rolled with oil and water, and wholly avoids the great waste of oil that has heretofore been unavoidable. Should it be required at any time to use the box as a dry box, that is to have the strip of metal pass to the rolls in a perfectly dry condition, it is simply necessary to open either or both of the cooks 14 and draw oif water until the liquid line drops down below holder 9.

15 denotes side plates which are provided with holes through which cross pieces pass. These plates protect the sides of the box from the wearing action of the edges of the coil of metal, and also adapt the box to the rolling of narrow coils of metal as well as coils the full width of the box. is to be rolled holder 9 is removed and a narrower one corresponding to the width of the coil to be rolled is substituted in its place. The side plates are moved inward close to the edges of the coil but not necessarily in contact therewith, and are locked in position by pins 16, which pass through the cross pieces. If required two or three narrow coils lying side by side may be rolled at the same time.

Having thus described my invention, I claim- 1. An oiling box provided with a holder to support a coil of metal and with a pipe 11 the lower end of which extends nearly to the bottom of the box, the upper end extending above the bottom of the holder and out through the side of the box so that in use water may be passed into the box but the liquid line will not be raised above the top of the pipe.

When a narrow coil 2. An oiling box having a holder to support a coil of metal and a pipe 11 the lower end of which extends nearly to the bottom of the box, the upper end extending above the bottom of the holder and out through the side of the box, a flange 3 on three sides of the box having an opening into the box at the lowest portion and a drip trough 5 also leading into the box arranged as described so that oil carried upward by the strip of metal and not consumed in use must pass back into the box.

3. An oiling box provided with a holder to support a coil of metal and with a pipe 11 the lower end of which extends nearly to the bottom of the box, the upper end extending above the bottom of the holder and out through the side of the box by which the liquid line is retained at the normal position, and a cook 14 by which the water may be drawn off leaving the oil in the box and permitting the latter to be used as a dry box.

4. An oiling box provided with cross pieces 10, a holder 9 resting upon said cross pieces and adapted to support a coil of metal, and side plates 15 which protect the sides of the box and are adjustable on the cross pieces.

In testimony whereof I affix my signature in presence of two witnesses.
